j 9 claims. `(el. 304;-24)

Mflihis invent-ion pertains to seat structures,` especially those `intended for use in Washing `the outer` side of` Windows; `the present application being a continuation of my application, Serial No. 707,253, iiled November l, 1946,

new abandoned. s s s Various types of window seats of this class have been proposed heretofore, but `the pr-iordeviceshave been subject to one or more objections, such as `ungainly` appearsance,` excessive weight, structural corriplexity,` cost of `manufacture, or shortcomings in features of safety and.

`"general practicality, s

` A he seat structure disclosed herein ischaracterized 'by lightweight, a simpleyet sturdy structural novelty` with ease of assembly and disassembly, and low manufacturing cost.

"One of the important structural `objects ofthe invention is the formation of a seat frame member `and a back guard member from separatelengths "of lightfweight metal `under each of theside portions 25, and these legs are pref-` tubing, feachbavinga pairof safely booksinterlitted t `with a pair of hooks of the otherto engage a' windowlsill jointly while at the samegtime'serving asa reinforcement and a `structural interconnectioriwfor the two members.

""Another object is the provision "of tubular legs 4and `aligned tubular spacing braces joined by a removablebolt means"therethrough acting to `rigidity both thelegs and braces yet permitting a dismantling of the seat for ship- `ping or stowage purposes."

Another object is the"`provision of a `thin seat 1member which rests upon thefseat frame and is held in position y by` passage therethrough of the aforesaid bracing spacers. p Another. objectis" the `provisionol tubular frame memybers, parts of whichareoffset in a certain manner forwin- 2,868,592 Patented Jan. 13, 1959 ing which is bent `intoa substantially uvshape complementary to that` of the guard member, so as to underlie the latter as in Fig. 1, with a rearward bight portion 24 (Fig. 3) substantially underlying the bight portionll of the guard, and a `pair of oppositely situated side arms 25 respectively underlyingarm portions `14--15, 17-18.Aof the guard, it beinglnoted that the lowered extensions 17, 18 of the guard are brought down in close proximity and near parallelism with the seat frame extensions 25, primarily to afford a maximum clearance so that the sliding sash-type windowmay .be loweredfullytothe limitpermitted by the legs offthe occupant of the seat, and `for the further purpose of `overlying a seat member 3'4, as will appear.

The forward endwise portions 25 of the tubular seat framearealso ilattened, as at- 26 (Figs. 1 and-2), and

erably permanently attached, as by welding or brazing, to

members 25. p t i "Preferably, each of theforwardlattened end portions 26 of the seat frame extensions, and at least a portion of `the'appurtaining hook 27,is provided with a rubber or "and`13` and their respective underlying seat trame portions "p25, the fends of these members 30 being chamfered or shapedto intertitclosely with the curvature of the tubuv braces are fitted. s

The legs 2S and bracing spacers 36 of each pair 'are provided with a tie bolt or rod 31 (Fig. 4) passing interiorly therethrough, and through the appurtaining frame lar members 12 and 25, for example, between which these ltubing; the tie bolts'being headed at their lower end`s32 dow-clearance, andiend portionsl ofitwhich are liattened` i and hooked to nest,v in closely fitted pairs. s

M `Additional objets and aspects of novelty and `utility reside details o f the construction and operation of the illustrative embodimentof thei device described in view of the appended drawing, in which:

Fig. l is a perspective View of a seat constructed in ac- Fig. 4 `is a fragmentary enlarged section oni` the 4lines i '4L-I4 of Fig. 2;

j Fig., 5` is a section on linesS-S of Fig. 1. s

s sThe novel seat structure 10is shown fully` assembled fin Fig. `1,` and consists of a back' or guard frame formed from a single length of ,metal tubing" bent into" U`-shape a rearward or bight portion `lliand opposite'side arms 12 and 13 respectivelyucurved downwardly `then forwardly, as at 16, to providefront' arms or oppositeend- Vwise projections 17 and 18, which lareboth flattenedas "at`i19, `and bent to provide hook members 20 cpableof engaging around the inner edge 21 of a window sill structure (Fig. 2).

The seat structure further includes a lower seat-frame member 23 likewise made of a single length of metal tubandbeingithread'ed attheir'upper ends to receive retainboard otherwise resting on frameportions 23, 242125, 26, and being also held down at its forward ends by theciosely overlying guardV arm s7174 and` l1S.

` Preferably, theinte`rttedfornested silland assembly jhooks` in each pair are removably secured together by "rneansofscrews 'engaged therein.

A -elarnping screw 36jis threaded into and through` the 55 llower reentrant'orrec'urving portions of both of the nested "Fig, 5 and'having a`head`37 fitted with a split socket to removably engage and rock upon a ball head on 'the screw,

hooks `of eachipair, said lscrews being ot' a type shown in asat 38. s

The clamp screws 36, themselves, will suiice to main- `tainthe nested hooks'of each pair in intertted or assembled relation sothatthere would bene danger of these hook parts disengaging if screws 3S wereomitted. s

However, since theclamp screw heads 37 are made removable for thosewho do'not wish to trouble usingone or both of the samen for added safety,.and in anticipation condition; ,and for4 purposesof safety, accidental separation of thehooks of each pair is to be avoided.

The manner in which the novel seat is intended to be installed and used on'the conventional window sill structure is rvthought to be'apparent from Fig. 2.

It will now be apparent that the novel seat consists of relatively few parts 'of simple structural character, namely aseat board, a pair of tubular frames made of single lengths of tubing secured together by means of interengaged sill hooks and a pair of spacers with tie bolts. Assembly and disassembly are equally simple. The tubing is utilized and joined structurally in a manner to alford a minimized weight with adequate strength, particularly at the critical hook formations (without which such a device would be dangerous to the point of impracticality). l

I claim:

1. In a window seat structure, a seat frame formed from a length of metal tubing curved to bring its opposite endwise portions into approximate parallelism, the ex-v tremities of said portion-s each being turned back to detine a sill-hook; a back-guard frame similarly formed from a length of metal tubing curved to bring opposite endwise portions adjoining a rearward bight into approximate parallelism, spacing and bracing means extending vertically from said seat frame, a rearward portion of said guard frame being supported on said spacing and bracing means above the horizontal level of the seat frame, said endwise portions of the back frame also being turned downwardly to extend into conjunction with the sill-hook portions of the seat frame, and the extremities of said downwardly-turned parts being turned back to dene hook conformations adapted to encompass the sill hooks on corresponding sides of the seat frame to form nested double hooks respectively adapted to hook onto the edge of a window sill, means for securing each pair of nested hooks against separation, whereby the nested hooks serve both as a sill-engaging means and a means for securing the conjunctive endwise portions of the two frames in assembled relation.

2. A seat construction according to claim 1 and further characterized by the provision of a at seat body adapted to rest upon said seat frame and having cutout portions closely intertting with said vertical bracing and spacing means to maintain the seat body in position upon the seat frame.

3. A window seat comprising a pair of U-shaped frames one adapted to overly the other in alignment to dene a seat frame and a guard frame therefore, a vertical spacing arm secured between the seat frame and overlying guard frame on each side of the seat structure, a at seat member resting on the seat frame and having a cut-out on each side thereof to intert with the spacing army on the corresponding side of the seat structure whereby to maintain the seat member in a predetermined position on the seat frame, said frames having their respective end portions turned into hooks, the hooks of the guard frame closely embracing the hooks of the seat frame in nested pairs on opposite sides of the seat structure, said pairs of hooks being adapted to hook onto the edge of a Window sill.

4. A construction according to claim 3 in which said guard frame has its opposite endwise portions turned down a substantial distance rearwardly of said nested hooks to overlie said seat member in proximity sufficiently close thereto to prevent substantial upward separation of the seat member from the seat frame.

5. A window seat comprising a seat frame formed by a singlel tubular member curved to provide opposite forward ends, a complementary overlying back and arm frame on said seat frame and formed by a single tubular member curved to provide opposite forward ends, the forward ends of said members on corresponding sides of the seat being flattened and hooked to overlap and jointly hook in nested pairs around the inner sill portion, and means common to each pair of nested hook ends for clamping the same to the inner sill portion.

6. A window seat comprising a seat frame having legs for standing on the outer sill portion, a -seat board carried on said seat frame, a back and arm frame on said seat frame, integral endwise extensions on said frames continuing forwardly land bent into interfitted nesting pairs of hook-shaped ends to encompass the inner sill portion, said hook-shaped ends being secured together, at least, by screw-clamp means threaded into each pair of ends for clamping the respective pairs of hooks to the sill.

l 7. In a window seat, a seat frame made of'a single length of metal tubing and having attached legs for standing on the outer sill portion, a back and arm frame on said seat frame and also made of a single length of metal tubing, braces secured to said frames, integral, oppositely situated sidearm extensions on said frames and continuing forwardly and respectively flattened and bent into opposite pairs of nested U-shaped hook ends to encompass the innersillnportion, said Lgt-shaped hook ends on corresponding Asides of the seat being secured together in nested pairs, and means threadably engaged in each said pair of ends for clamping the U- shaped hook ends to the sill.

8. A window seat comprising a seat frame having legs for standing on the outer sill portion, a seat member carried on said frame, a back and arm frame above said seat frame, opposite, integral side-arm extensions on both sides of said frames and continuing forwardly into conjunction and bent into recurving nested sets 0f hooks to engage the inner sill portion, adjustable means operatively engaged with each set of hooks preventing separation of the same and for clamping the same to the sill, and spacing members respectively aligned with said legs between the seat and back frame and attached thereto for'maintaining the arms at proper distance from said seat frame.

9. In a window seat, separable back and seat frames of approximate U-shape and each made of a continuous elongated member having opposite free ends bent down into a sill-engaging hook, the hook on each side of said back frame being of a size to receive Within it in nesting relation the hook on the corresponding side of the seat frame; sill clamping screw means threadedly engaging and conjoining each pair of nested hooks; brace means interposed between the seat and back frames, and threaded means removably securing at least one of said frames to said brace means.
